Papillary carcinoma of the thyroid.

Between 1954 and 1993 503 patients with papillary carcinoma of the thyroid were treated at the Department of Otolaryngology-Head and Neck Surgery of the Beilinson Medical Center. Two thirds of these patients were women. The median follow-up period was 10.3 years. In more than 30% of cases the tumor was discovered because of the presence of an enlarged lymph node and/or invasion to adjacent structures. Total or near-total thyroidectomy was performed in 381 patients. The 48 patients in whom it was necessary to perform a reoperation had a significantly higher complication rate. Multicentricity was found in 65% of those cases in which both thyroid lobes were available for histologic examination. Nineteen patients were found to have a "tail" cell variant, 223 had a pure papillary variant, and 261 a follicular variant. The mortality rate was 6.2% 15 years after initial therapy. A number of factors-age, size of tumor, presence of distant metastases, "tall" cell variant, and type of surgery-were found to be significant predictors of survival. After almost 40 years of experience in treating more than 500 cases of papillary cancer, we have come to the conclusion that the surgical approach should be aggressive.
